SPECIFICATION forming part of Letters Patent No. 494,052, dated March21, 1893.

7 Application filed August 13, 1892. $erial No. 443,011. (No model.)

To all whom it may concern.-

Be it known that we, GUsTAVE BAUCHE and HENRI BAUGHE, citizens ofFrance, residing at Paris, in the Department of the Seine, France, haveinvented a new and useful Improvement in Cloth-Napping Machines, ofwhich the following is a specification.

Our invention relates to that class of mechanism employed in forming anap upon woolen fabrics, and the purpose of said invention is to providesimple, and efficient means whereby this nap may be produced through theaction of what may be termed metallic teasels.

The invention consists to this end in a novel construction andcombination of mechanical parts by which the relative action of thefabric and of the metallic teasels is produced under conditions of themost favorable character, resulting in the production of a uniform napof any desired length and strength throughout every part of the surfaceof said fabric.

It is, also, one purpose of our invention to provide means whereby thelength and depth of the nap may be regulated wholly by frictionaldevices and to so organize the mechanical parts that the nappingmechanism shall receive its rotative movement from the travel ofthe'fabric itself.

In order that our invention may be clearly understood by those skilledin the art, we will now proceed to describe the same in all its details,reference being made to the accompanying drawings, in which Figure 1, isan end elevation of a machine embodying our invention. Figs. 2, and 3,are diagrams illustrating the means whereby operative movement isimparted to the nap-producing members or teasel-cylinders; and Fig. 4,is a vertical section of the machine in the line AB, Fig. 1.

Referring to said drawings-upon the shaft 0 is keyed a pulley which isbelted in any suitable manner to a source of power, said shaft beingusually provided with two pulleys, 1 and 2 one of which is loose and theother tight, or keyed upon said shaft in the ordinary manner. Rigidlymounted upon said numerals 1 to 12, inclusive.

shaft are two disks D, D which form the support for twelveteasel-cylinders of metal, which are designated in the drawings by theThese numerals are placed in the order of succession indicated in Fig.1, that is to say, in the order in which said numerals read, 1, 2, 9,10, 3, 4, 11, 12, 6, 5, 7, 8. The two disks D D derive their. rotarymovement from the shaft 0 and the teasel-cylinders carried by thesedisks are thus caused to partake of a double movement, one movementbeing that of translation, or in other words the movement which is givenby the revolution upon their axes of the disksD D, and a second movementwhich consists of the rotary movement of said teasel-cylinders upontheir own axes. The six teasel-cylinders designated by the numerals 1 to6, inclusive, are geared at the left hand of Fig. 4, by means of smallgears or pinions 3 upon their ends which mesh with a gear E, also shownin Fig. 2. The six remaining teasel-cylinders designated by the numerals7 to 12, inclusive, are geared at the right hand of said Fig. 4, with agear E having the same number of teeth as the gear E (see Figsl 3 and4). The two gears E and E are loose upon the shaft 0 and two pulleydisks or plates F and F are keyed upon these gears E and E. The twelvemetallic teasel-cylinders turn upon their own axes whenever they are incontact with the fabric upon which the nap is to be formed, the movementof which provokes, by its tangential engagement, the axial revolution ofthese teasel-cylinders. The points of contact of said tissues or fabricswith said teasel-cylinders are so arranged upon the machine that, whenin operation, there shall always be six teasel-cylinders, viz., thosedenoted by the figures 1, 2, 3, 4, 5, and 6, in Figs. 1 and 2 incontact, and six denoted by the figures 7, 8, 9, 10,11,12 out of contactwith said tissue, the purpose being that the six teasel-cylinders whichgear upon the left hand of Fig. 4 and which'are in tangential contactwith the tissue, shall derive their positive rotation from the fabricand shall transmit the same with diminished power to thoseteasel-cylinders which are geared at the right hand of Fig. 4, and whichare out of contact with the fabric.

The contrary effect is produced to that described above whenever theteasel-cylinders which are geared upon the right of Fig. 4 of thedrawings, and which are designated by the numerals 7 to 12 inclusive,make contact with the fabric and receive their positive revolutiontherefrom, transmitting the same with whatever degree of diminution inpower may be produced by friction or other causes to theteasel-cylinders geared at the left of said figure, and designated bythe numerals 1 to 6 inclusive, the latter teasels being out of operativecontact with the fabric. The particular functional advantages residingin these teasel-cylinders and their capacity of variable power dependupon the following points: Those teasel-cylinders geared at the.

left of Fig. 4 and designated by the numerals 1 to 6, inclusive, beingin contact, tangentially, with the fabric to be napped, receive theirpositive rotation from the movement of the fabric and become themselvesdrivers, or parts from which motion is directly communicated. Saidteasel-cylinders transmit 'movement to the gear E which is loose uponthe shaft 0, but which forms part of the pulleydisk or plate F. Thispulley-disk, pressed bya friction-gear A, communicates rotary movementto a shaft G,by means of pulleys H and H which are of differentdiameters, one of which is provided with a click-pawl and ratchet I,keyed upon said shaft G, the pulleys H" being movable on said shaft. Theshaft G transmits its movement of rotation to the gear E, which is alsoloose upon the shaft 0 but forms part of the pulley-disk F. Thismovement is accomplished by means of the two belt-pulleys J and J whichare of the same diameter and the friction -pulley B, which is held witha suitable pressure against a friction-face 4 upon the pulley-disk T.The teasel-cylinders indicated by the numer ale 7 to 12, and gearing atthe right hand of Fig. 4, being in mesh with the gear E, are thus causedto have a variable movement, as compared with those teasel-cylinderswhich have their gear connections at the left of Fig. 4, and are shownby the numerals 1 to 6 inclusive.

Whenever the teasel-cylinders having their gear connections at the righthand and designated by the numerals 7 to 12, inclusive, come in contactwith the fabric, they receive positive movement direct and become intheir turn transmitters of motion, theirrotary movement being thusimparted to the gear E which is loose upon the shaft 0, but forms partof the pulley plate or pulley-disk F. This pulleydisk, pressed by thefriction-gearG, imparts movement to the shaft G by way of the pulleys Jand J, which are equal in their diameter. The shaft G gives a variablemovement to the friction-gear A by means of the two pulleys H" H", whichare of different diameters, and by the ratchet and click-pawl I, fixedupon the axis L of the friction-gear A. This friction-gear bears withits working face upon the pulley-disk F, forming a body-portion of thegear E, which is provided with one hundred teeth, and is movable uponthe shaft 0, its teeth having their engagement with those pinions uponthe teasel-cylinders which gear at the left hand of Fig. 4 and which arebetween the points of contact with the tissue as shown in the drawings.This arrangement gives to these teasel-cylinders a movement which isdifierent from the movement imparted to the remaining members of theseries which are designated by the numerals 7 to 12 inclusive.

The resistance of the teasel-cylinders and the variable length and depthof the nap formed upon the fabric are controlled by the pressure ofshipping levers K, K mounted upon fulcrums L and L, respectively, uponwhich levers are mounted the friction-gears A, B, respectively, whichhave a frictional bearing upon the two disks F and F. The operativecontact of these frictional devices is controlled at will by means ofmovable key bolts M, M each one carrying a spring N, which has bearingagainst one of the shipping levers K, K.

The action of the parts last described is controlled by the adjustmentof a small handwheel 0, having a female thread which receives the malethread formed upon the end of the key-bolt M, or M, described above,there being one of said hand-wheels and keybolts to each of said leversand the two together furnishing independent means whereby any desiredadjustment may be given, as circumstances may require.

In this description we have given no explanation and paid no attentionto those details of mechanical parts whereby the travel of the fabricand woolen goods is provided for, as these are taken from and receivedon any suitable form of rolls or large pulleys 5 and guide rolls 6 madeof wood or any other suitable material, and which are so similar tothose already used in napping-machines that they require no specialdescription.

Having thus described our invention, what we claim is In a nappingmachine, the combination with a shaft, of two spur-gears loose thereonand having a difierent number of teeth, a series of teasel-cylindersarranged concentrically with relation to said shaft, each alternate pairhaving pinions at one end gearing with one of said spur-gears, and theremaining pairs being geared in like manner to the other spur-gear, aseries of rolls and guide,- rolls whereby the fabric is brought intocontact with one of the series of pairs, means for feeding the fabric toimpart revolution to IIO the said pairs of teasel-c'ylinders, apulleydisk forming part of the spur-gear meshing In testimony whereofwe'have signed this 10 specification in the presence of two subscribingWitnesses.
